Perth Agencies and Government Bodies Race to Fix Duplicate Image Problem Across Digital Records This Week

Digital records managers across Perth spent the first days of July scrambling to identify and replace thousands of duplicate images embedded in public-facing databases, heritage registers and planning portals, after a systemic audit flagged the scale of the problem. The issue, which has compounded over years of rapid database migration, affects everything from property listings on the Western Australian Planning Commission's online portal to cultural asset records held by the City of Perth.

The timing is not coincidental. The state's Metronet expansion and the ongoing AUKUS-linked infrastructure build-out around HMAS Stirling at Garden Island have generated an extraordinary volume of new project documentation since 2024 — environmental impact images, site photography, engineering schematics — much of it ingested into legacy content management systems that were never designed to deduplicate at scale. When agencies copy records between platforms, identical images frequently receive separate file identifiers, bloating storage costs and, more seriously, creating version-control errors that can attach the wrong image to the wrong record.

What the Audit Found This Week

The State Records Office of Western Australia, based on Roe Street in Northbridge, circulated a technical advisory on July 2 to agency records managers outlining minimum requirements for image deduplication ahead of a broader digital continuity review scheduled for later in the financial year. The advisory does not carry the force of a formal directive yet, but records managers at multiple agencies confirmed this week they had begun internal sweeps of their repositories.

At the City of Perth, staff responsible for the heritage buildings register covering the CBD's east end — including the stretch of Hay Street between Barrack Street and Victoria Avenue — identified a batch of mismatched facade photographs attached to incorrect lot numbers. The error class is common: when a contractor uploads a series of images sequentially, numbering errors in batch-upload scripts cause transposition. The City has not publicly quantified the affected records.

Meanwhile, Landgate, the state's land information authority headquartered in Midland, has been running its own deduplication pass on aerial survey imagery collected during the 2025 cadastral resurvey of the Swan Valley. Landgate's imaging library now holds more than 4.2 million raster files, a figure that has roughly doubled since the 2019 financial year, making manual quality checks impractical without purpose-built tooling.

The Practical Stakes for Perth Residents and Developers

For most Perthites, duplicate images sound like an IT housekeeping issue. The real-world consequences are less abstract. A development application lodged with the Western Australian Planning Commission that carries the wrong site photograph — say, an image of a Scarborough beachfront lot attached to a Baldivis subdivision application — can delay approval by weeks while planners request corrected documentation. In a housing market where median dwelling prices in Perth's middle ring have remained under sustained upward pressure through 2025 and into 2026, even a four-week delay on a subdivision approval has measurable financial consequences for developers and, eventually, buyers.

Insurance assessors and heritage consultants working out of offices along St Georges Terrace have flagged similar concerns. Duplicate or mismatched images in heritage overlay databases can, in edge cases, trigger incorrect heritage classifications that affect what modifications owners are permitted to make to properties listed under the Heritage Act 2018.

The push to clean up these records also has a budget dimension. Cloud storage costs for state agencies are billed centrally through the Department of Finance's Whole of Government ICT arrangements. Eliminating redundant image files across even a handful of large repositories can reduce ongoing storage expenditure meaningfully, a consideration that carries weight given the WA government's stated aim of extending its budget surplus position into the 2026-27 financial year.

For developers, architects and heritage consultants dealing with Perth agencies right now, the practical advice is straightforward: recheck any digital submission lodged before June 30 to confirm images are correctly labelled and sequenced, particularly for applications involving Metronet corridor sites or Swan Valley rural lots where the volume of recent surveys is highest. Agencies are actively correcting their own backlogs, but a correctly labelled submission will move faster than one that lands in a queue already under audit scrutiny.
